Application filed February 25, 1914. Serial No. 820,940.

To all whom it may concern:

Be it known that I, FREDERICK JAMES MCKENZIE, a subject ofthe King of Great Britain, residing at 4: Great Portland street,

carriages, orthe like (all of which I will hereinafter refer to under the term can riage) in sections 21-6.. in suchwise that such frames or frame members are capable of adjustment, or capable of forming frames of various lengths so asto suit various types a V be curved or formed into any desired shape or sizes of the carriage body; and the journals or hearings (or housings for said journals or bearings) for the axles of the wheels may be so mounted or carried on said frames or frame members that "said journals or bearings or the housings thereof are capaable of adjustment toward and away from one another so as thusto enable the length of the wheel base to be adjusted (2'. e.

lengthened .or shortened) as may be re-' quired. i a

Referring to the accompanying drawings: Figure 1 is a view in side elevation of a carriage .(namely a baby car) provided on each side of the car with a frame or frame member; each of which frames or frame members is constructed, according to the present invention,- in three parts telescopically combined to form a frame orframe memberof the total length desired; which 3 parts as shown in Fig. 1 have been slid together so as to form a frame member of shortened length on. each side i. 6. so as tosuit a short car body as-shown in this figure. Fig. 2 is a view in side elevation of a carriage (namely ababy carriage) the body of which is longerthan that shown in Fig. 1 and the telescopic frame or frame member according to thisinvention (at each side) is shown extended 'so as to form a longer wheel base i and suit this longer form of carriage body.

Fig. 3 is a localzdiagrammatic view in side elevation of my present. invention carried into. practice with the telescopic frames or frame members so formed or provided. with journals or bearings or housings for said journals or bearings for the axle of one of the-wheels that said journals or bearings or housings thereof are capablev of adjustment with respect to the journals or bearings of the other wheel to thereby enable the length of the wheel base to be adjusted.

Referring to Figs. 1 and 2: According to the construction shown in the drawings each said side frame comprises three principal components or'members viz; a central cona meeting member termed the central member A and two end members A and A which latter at their inner ends aretelescopically combined with (or otherwise adapted to which they are adjusted; while the other end a i. e. the outer end of each end member may bolts or looking pins through said apertures so as to secure each end member at any de sired position relatively to the central member'-see for example the arrangement illustrated' in Fig. 3. The other end of the two endmembers A A may be curved or formed to any desired shape for example somewhat in the form of a spring and from such end T the body B of the carriage may be suspended advantageously through the medium of a spiral suspension spring C the other end of each of which is attached to a rigid arm D carried on the body B of the carriage; or

"said body may be otherwise suitably at tached to such end of each said end member.

Furthermore, if desired, a tension or other suitable spring or springs Z may be attached at one end to the lower part of the body B of the carriage andat the other end to the cenbody B. The journals or bearings for both the Wheel axles may be carried on the central or attached on said central member or on end members. 7 As aforesaid the end members A A may be made either tubular or solid and if desired same may beformed in suchwise as to act as springs. i

Referring to the arrangement illustrated in Fig-3; theend member A telescopically combined with the central member A is i *the like.

locked-in the desired position with respect to said central member 'A by means of the pass through the two members A A a series of holes being provided in the central member A to allow of the adjustment of the sleeve along said member; and this sleeve or bracket E carries the journal or bearings V sleeve or bracket E and bolts F which latter G fOI one axle H, while the other axle I is V 1 carried in a bracket J fixed to the said central member A on each side of the carriage.

By this invention I can therefore adopt a standard size (or more than one size if desired) of such sectional frames whether. made m3 or other number of parts; and

such standard size can be adapted and used for forming frames of different lengths to suit different sizes and types of carriages, or

gether in any suitable manner either in the I process of manufacture or when it is desired to put same together to form the complete frame in building the carriage; for example the two side frames may be rigidly connected by one or morecrossbars which may be either tubular or solid and located at any suitable point or points between the two side frames for instance a single cross bar may be employed and. attached at right angles to the central member of each of the two side frames and located midway or thereabouts along the length of said side frames; Or

said frames or frame members may be braced or held together by diagonally disposed rods or tubes crossing each other, or otherwise braced or held together; and ifdesired such cross bars or tubes or brace bars or tubes may be arranged to be attached to and'de-' tached from the said frame members in any suitable manner such as screwing thereinto or by screw andnut or clips or other equivalent or suitable arrangement.

Obviously the threeparts A. A A arranged and adapted to slide along one anothertelescopically or otherwise to form Furthermore two such tubular or 7 other side frames (such as made from the three parts A A A maybe connected toeach frame or frame member of the desired length, should be so formed or fitted together as to prevent any turning movement axially of one part relatively to one another; and if the said parts A. A A are circular in cross section then anyrelative turning movement between these parts may be prevented by any suitable means as for example as shown in Fig. 3 by the bolts F passing through coincident holes in the two members A. A while the parts A. A are fixedly secured together by any suitable means such-as brazing riveting or clamping; or such members A. A A .'or the parts thereof where same slide; upon one another telescopically or otherwisemay be formed of other than circular shape in cross section as for example the parts A. A should be square or rectangular or oval or other suitable shape (other than circular)' in cross sectionand the part A if tubular formed with correspondingly shaped bore or opening therethrough ortherein.

That I claim is, for supporting the body of a carriage of the kind hereinbefore referred to '1.,A frame or frame member for each side of a carriage, constructed of a pluber, of the desired length to suit any par-' adjusted,substantially as described.

2. A frame or, frame member for each side of a carriage, constructed of a plurality of parts which collectively form the total length of said frame or frame member and which are arranged and adapted to slide telescopically or otherwise along one another to form said frame or frame member, of thedesired length to suit any particular length of carriage body or any particular length of wheel base, the end parts of the frame member directly connected to the body of the carriage being shaped to form C-springs on Whichthe said body rests, means to secure said parts firmly together in any position to'which they are adjusted,

and-journals orbearings (or housings for said journals or bearingslfor the axles of the wheels, so mounted on the said parts of said frame or frame member that said journals or bearings (or the housings thereof) arecapable of adjustment toward and away from one another, substantially as described. f3. A frameor frame member for each side of a carriage constructed of a plurality of parts which collectively form the total length of said frame or frame member and which are arranged and adapted to slide telescopically or otherwise along one another to form said frame or frame member, of the desired length to suit any particular length of carriage body or any particular length of wheel base, means to secure said parts firmly together in any position to which they are adjusted, and bearings for the wheel axles firmly. attached to the central part of said frame, substantially as described.

4. A frame or frame member for each side of a carriage constructed of a plurality of parts which collectively form the total length of said frame or frame member and which are arranged and adapted to slide telescopically or otherwise along one another to form said frame or frame member, of the desired length to suit any particular length of carriage body or any particular length of wheel base, means to secure said parts firmly together in any position to which they are adjusted, bearings for one of the wheel axles fixedly attached to the cen tral part of said frame, and bearings for the other wheel axle adjustably attached to said central part, substantially as described. v

In witness whereof I have hereunto set my hand in presence of two witnesses.
